The invention relates to a group table slide particularly to one whereinnumerals, indications or illustrations on a tongue or the like movablerelatively to an outer part are visible in openings in the outer part sothat the purpose or the relation of the numerals or the like relativelyto other numerals or the like is immediately or easily ascertainable.Table slides of this character with only a, single tongue are known. Inorder, however, to solve certain problems, for example, to carry outwage calculations, interest calcula tions and so forth, a plurality oftongues is necessary if the table slide as such is not to acquire a toounpracticalsize. When a number of tongues are used they must be arrangedin groups one above the other in a guide sleeve or the like.

In order that the'reading of the numbers is easily possible from eachseparate tongue, each tongue is provided with one or more apertures Owhich enable the figures or other indications of tongues located atalower level in the pile to be seen through the openings in the tongueslocated above them and in the tongue guide. In this manner verymanynumerals or other indications 5 can be arranged so as to be easilyreadable with slides of comparatively small dimensions.

The novelty resides in the fact that pins or the like engage with theslots of the tongues which prevent the tongues from being withdrawncompletely from the guide sleeve.

tongues directly following one another are directed' towards difierentends of the sleeve so that successive tongues can only be withdrawn fromdifierent sides of the sleeve. In this manner there is obviated theliability when withdrawing one tongue of withdrawing at the same timethe adjacent tongue as the tongues are held in the sleeve by friction sothat they do not lose accidentally the position which they have onceassumed. At each end of the sleeve a notch is provided for each tongueadapted to be withdrawn at the corresponding end, whilst each tongue isprovided with notches and also a handpiece, which projects into thenotch of the sleeve.

Each tongue may also be engaged by itself in a notch of the sleeve.

In the drawings are illustrated diagrammatically a few examples ofconstruction of the subject of the invention.

The slots of two The table slide is provided with a sleeve-like guide Iin which openings 2, 3, 4 are provided. The openings 3 and l areprovided near the two ends of the guide I. The openings 2 may beprovided at suitable points of the slide but they are preferablyarranged in line with the openings 3 or 4, as in this manner thepossibility of reading the various inscriptions is facilitated, as theview can remain fixed on a definite point. In the guide I tongues 5 areso arranged that successive tongues can be withdrawn towards difierentends. Each tongue has openings 1 near its ends which correspond in sizeand position with the openings 2, 3, 4 so that the openings of all thetongues and the sleeve-like guide register with one another when all theslide tongues are pushed fully into the guide I. At the ends of theguide and tongues are formed recesses or notches 9 which correspond withone another. At separate points of the difierent slide tonguesuninterrupted points 8 remain at which the corresponding tongues can begripped separately and withdrawn. The points in question are located atdifferent ends according to whether the corresponding tongue is to bewithdrawn at one end or the other.

In order to prevent the tongues 5 from being withdrawn completelysuitable stops are provided which in the examples of constructionconsist of elongated slots l2 formed in the tongues and of clamps orscrew pins l5 passing through the guide and all the slots l2 of thetongues. The withdrawability of the separate tongues towards one end andother tongues towards the other end is facilitated by the provision ofhandpieces 8 on the tongues and it is also possible, if desired, towithdraw two tongues simultaneously towards both ends so as to enableindications on difierent tongues to be read through the openings 3 and 4and compared with one another.

The openings 2 are for example adapted to render visible guide numberson the tongues, by means of which the setting of the tongues in theguide can be eflected. The remaining openings 3 and l expose theindications to be obtained. When withdrawing any one of the tongues ofthe pile and setting this to the guide number these indications caneasily be read through the openings 2 and 3 or t and the openings l ofthe tongues located in the position of rest above this tongue. All thetongues form a continuous table of which the indications are not locatedin one plane but stepwise above one another, so that the table has ahandy form. In addition definite groups of indications when reading areseparated from all remaining indications for which reason it is notnecessary to search for them tediously but, without the possibility ofany error being liable to occur they are immediately visible. When thetable slide is to be constructed for one side only the openings on theback are omitted, but it indications are also to be provided on the backof the tongues, it will be understood that openings 2, I, 4 must beprovided both in the front and in the back of the sleeve I. In Fig. 1separate openings 2 are provided for the guide number or the like, whilethe openings 3, 4 and I are interrupted by strengthening bars H whichare provided with slots [2. It is however also possible to usetransverse openings ll (Fig. 4) and the slots II are located on bothlongitudinal sides. The guide number or the like in this case appears atone end of the openings 3 and 4 (Fig. 5).

The example construction in Figs. 1 to 3 is constructed as a wagecalculating slide. When withdrawing one tongue 8 the hour number of theworking time appears in the opening 2, while in the openings 3 or 4there can be read the total amount corresponding with the particularwage which is obtained by the working time multiplied by the wage perhour noted adjacent the opening. Laterally oi the openings 3 and 4 theremay also be noted the wage for fractions of hours, which it necessarymust be added to the total amount.

The example of construction in Fig. serves to determine the interests oifixed interest bond papers at various rates of exchange and diirerentperiods of time. The guide number indicated at the upper edge of thetable, preferably printed in another colour indicates the rate ofexchange oi. the bond paper whilst the interest is indicated at thegripping surfaces 01' the various tongues. In the openings I or 4 thereappear laterally of the remarks on the sleeve regarding the years stillremaining 0! the paper indications regarding the interests, 1. e. theaverage of interest amounts and gain on exchange on release. When usingthis table slide the tongue bearing the interest of the paper on thegripping point is withdrawn to the corresponding side until the rate ofexchange has been set at the upper end of the opening. The interest isthen read in the opening adjacent the number or years 0! the periodstill to run indicated on the sleeve. This slide is mainly of advantagefor banks by reason oi the saving in time.

From these figures it will be seen that in a comparatively small spacean extremely large number of indications or numbers can be provided sothat the slide enables the calculations in question to be made within avery wide range whilst being of small dimensions.

In the form of construction in Fig. 4 the slide forms a notice tablewhich enables entries of every type to be found easily. In theconstruction as telephone slide it enables the entries oi addresses andnumbers of telephone subscribers, which can be entered in lead pencil tobe again found immediately by moving the slide tongues which areprovided at the gripping points with the corresponding letter of thealphabet. When the note is no longer required it can be erased easily,whilst indications which are always required may be printed. This formof construction may also be used as an exchange record and for manyother purposes having entries changing according to a table.

The slide may be made 01 metal, celluloid, or any suitable material,paper or the like and adapted in shape to the purpose in view.

What I claim is:

A group table slide comprising a sleeve-like guide having a plurality oiopenings therein and a plurality of superposed tongues in said guideeach having a plurality of openings therein, said openings being oi suchsize and so arranged that when all the tongues are arranged in the guidecorresponding openings in the guide and tongues are in registry, each ofsaid tongues being provided with a longitudinal slot, said slot in thesuccessive tongues extending toward opposite ends of said tongues, pinsin the guide one ad- Jacent each end thereof, said pins passing throughthe slots of alternate tongues, said tongues being in mutual contact andthe outermost tongues being in contact with the guide and means on theends of said pins and engaging the outer face of said guide for pressingsaid guide and tongues together so that all the tongues are held byfriction against casual movement, said tongues being adapted to be movedsuccessively from opposite ends of the guide.
